New laws

In Chapter 1, the author outlines the differences in the Cultures of Psychology and the Legal System by explaining the differences between rulings and data. One of these explanations is that precedents influence current rulings in cases. Discuss the possibility of cases for which there are no precedents and cases for which new laws are being enacted, such as gay marriage and child custody. Who has the rights to the child when both parents are mothers? Fathers? What about marriage between a naturally born male or female and a postoperative gender reassigned male or female? What happens in cases for which there are no precedents? How would students rule if they were judges?
